    copied!<p><strong>UPDATE:</strong> My "problem" was due to a bad assumption about the class I was using reflection upon. My question below is nonsensical as it doesn't act that way. But I am leaving it here in case the code snippet is useful.</p> <p>I am using reflection to generate viewmodels off of a compiled class that resides in a <strong>separate</strong> assembly. Most everything is working except the types I get back from the compiled assembly shows an interface instead of the class that is the concrete implementation of the interface.</p> <p>For example, in the compiled assembly I define a property like:</p> <pre><code> public List&lt;String&gt; strings { get; set; } </code></pre> <p>Using reflection, I have been able to generate a corresponding property (and complete class) that looks like this:</p> <pre><code> public ICollection&lt;String&gt; strings { get; set; } </code></pre> <p>I get the types doing this (severely snipped for brevity):</p> <pre><code> Type value = &lt;...some passed in type...&gt; String types = String.Join(",", value.GetGenericArguments().Select(t =&gt; t.Name).ToArray()); String.Format("{0}&lt;{1}&gt;", value.GetGenericTypeDefinition(), types); </code></pre> <p>Is there any way using the Type object to determine what concrete implementation was used for the interface returned? I am guessing no but thought I would ask.</p> <p>If there is not a way, I am thinking of using a "most likely implementation" look up for a given interface (i.e. you pass in "ICollection", I translate that into a concrete "List") unless there is a better suggestion???</p> <p>A "perfect" solution isn't necessarily required as this is used to generate Controllers, Views, and ViewModels (with automapper and Kendo UI) using T4 templates. So if there are a few things to clean up, that is fine. So any suggestions that get me close are welcome.</p>
